It is to be noted that the current analysis has been carried out on ideal images devoid of any foreground. We also performed our analysis at a single redshift and in a single frequency channel. The information content is expected to improve with the inclusion of more than one redshift with multiple frequency channels at each redshift. In a recent work [1]} the authors showed how using multiple frequency channels and performing the analysis using Betti numbers alone in 3D cubes can improve the observation time required for performing such an analysis. Moreover, we used averages of the statistics over field thresholds, thereby integrating the threshold information. The full potential of these descriptors can be exploited if we use the versus threshold information and perform the analysis by integrating our statistics in a 21cm based inference framework [2]} such as 21CMMC [3]}. The full analysis with inclusion of foreground and a wider astrophysical parameter space of EoR [4]} will be carried out in a subsequent work in order to compare the constraints with those obtained from power spectrum in [3]}. Our analysis using a combination of Minkowski tensors in 3D and Betti numbers on observed 3D cubes is underway. Through this study we have shown that a morphological description of even a single image at one redshift and a single frequency channel from the EoR can help us constrain EoR parameters and can serve as a promising statistical tool.
